5. Cali Lewis

Cali Lewis possesses the kind of success story that would make anybody envious, as she now ranks among some of the best and brightest within the podcasting world — as well as one of the hottest women in tech. Cali, along with husband Neal, started up a website devoted to short tech-based podcasts entitled GeekBrief.TV, despite the fact that the two had absolutely no experience with video production. Yet, Cali’s plucky demeanor and drop-dead gorgeous looks ensured the show’s success, and — having gone from a viewership of a couple thousand to millions of downloads a month — the couple was able to quit their full-time jobs and focus their time exclusively on the site. Cali has been keeping busy in other avenues as well: In addition to taking over for Amber MacArthur on the final episodes of TechTV’s Call for Help, she has also launched a tech-advice blog entitled "Dear Cali," appeared on Ustream.tv, and started a podcast show devoted entirely to Apple’s iPhone.
